From Skeptical to Evangelist in Two Weeks

I thought this was solving a problem that didn't exist. Then my wife got a call from someone who knew our address, our kids' names, and our travel schedule claiming to be from our security company. She hung up and used Kibu to check obviously fake. I downloaded it that night and we've added our whole extended family since.

The simplest security solution

As someone over 50 and I appreciate how easy Kibu make identity verification and the interface is user friendly, and I don’t feel overwhelmed by tech and my only complaint is that I wish there were more tutorials available to maximize its features

Perfect for tech-savvy parents

I wanted to ensure my kids know who they are chatting with, so I introduced them to Kibu and the pods feature allows us to verify any group they’re in without hassle. They love using it and it keeps me at ease and it must have for families with kids

The Security Phrase concept is genius

Most verification apps make you memorize a static PIN or use biometrics that don't work across devices. The rotating Security Phrase means there's no permanent secret to leak or forget. I've watched my dad struggle with password managers for years, and he understood Kibu in about sixty seconds. That's the real test.

Finally retired the family password

Our family had been using the same secret word for years, and half of us could never remember it anyway. I really like that the Security Phrase changes instead of staying permanent. It feels more useful for the kind of impersonation scams people are dealing with now.
